The ground is shifting and sinking under Iran’s capital, Tehran.
A recent study based on analyzed satellite data shows that the Iranian capital is sinking at a rate of 10 inches per year
Tehran is sinking. This is not a metaphor connected to American sanctions or the drop in oil prices, but the conclusions of a recent study that analyzed satellite data about the Iranian capital.
It found that some parts of the city are sinking into the ground at a rate of up to 25 centimeters (nearly 10 inches) a year. The researchers also found that the sinking areas are expanding and could reach the city's international airport.
The research by two scientists from the GFZ German Research Center for Geosciences at Potsdam was accepted for publication by the scientific journal Remote Sensing of Environment. The findings were also published on the website of the journal
Nature. The researchers used satellite tracking data from 2003 to 2017 to track the rate of land subsidence in
Tehran.
A previous study linked the sinkage to the depletion of the groundwater aquifers under the city, which are being pumped to irrigate the fields surrounding the capital and to supply water to the city's 13 million residents.
